This is awful it left my hair sticky and coated and also made it dry and damaged at the same time. I have fine low porous hair this did the opposite of what it says its supposed to do.

Must have

GET IT. if you have that flaky white stuff in your hair that’s not dandruff, that is build up from natural oils form your head and from your shampoos and whatnot. This is a very concentrated shampoo that cleans it out in one wash. I’ve always struggled with it and now I use this about once a week and it stays away!

Really great detoxifying mask for any product build up in the hair. Enjoyed using and noticed it would keep my hair fresh for longer.

A weekly must before K18 leave in treatments

In order to get the best results with K18 leave in treatment, you need to get all the build up stuff out so that the treatment can penetrate. It's my first time buying this product as I used other prep items but this one is best matched with K18.

The Best!

This is the BEST shampoo I’ve ever used. I have semi fine low porosity 3b/c curly hair that is prone to build up and nothing not even bentonite clay was removing my build up. Now products and conditioner sinks in easily! conditioner like a dream. My new holy grail! cqncan soak up my scon

Amazing Detox Shampoo!

I have the driest and frizziest hair and this wonderful shampoo not only did not dry out my hair and scalp, but also hydrated my hair perfectly! I will buy it again and again!

Holy grail clarifying shampoo

This is a great clarifying shampoo. I feel it leaves my hair very clean but doesn’t make my hair feel super dry like other clarifying shampoos do. I also like the fragrance of this shampoo

Forever buying & using this

I’ve been using this for a few months now. My scalp usually still smells after a good wash (even scrubbing hard) but this has made my hair and scalp smell so much better. It actually smells like I’ve washed my hair. It’s non-greasy, non-irritating, and overall an amazing shampoo that CLEANS your scalp and hair. I plan to continue purchasing this as long as possible. It doesn’t have a very strong scent, but it doesn’t stink either. It really gets your head clean.
